Numerous studies have described improvements in speech understanding when interaural time differences (ITDs) and interaural level differences (ILDs) are present. The present study aimed to investigate whether either cue in isolation can elicit spatial release from masking (SRM) in a speech-on-speech masking paradigm with maskers positioned symmetrically around the listener. Twelve adults were tested using three presentations of the Listening in Spatialized Noise-Sentences Test, with each presentation modified to contain different interaural cues in the stimuli. Results suggest that ILDs provide a similar amount of SRM as ITDs and ILDs combined. ITDs alone provide significantly less benefit.
许多研究描述了在存在耳间时间差 (ITD) 和耳间强度差 (ILD) 时，言语理解能力的提高。本研究旨在探讨在使用位于听众周围对称位置的掩蔽器的言语掩蔽言语掩蔽范式中，单独的线索是否可以引起空间掩蔽释放 (SRM)。12 名成年人使用空间噪声句子测试的三种呈现方式进行了测试，每种呈现方式都对刺激物中的不同耳间线索进行了修改。结果表明，ILDs 提供的 SRM 与 ITDs 和 ITDs 组合提供的 SRM 相似。单独的 ITDs 提供的益处显著较少。
